TO ALL WHOM IT'MAY CONCERN:

Be it known that'I, WILLIAM S. LOUGHBOROUGH, of Rochester, in the county of Monroe, and State of New York, have invented a new and useful Improvement in Water-Proof Leather Cement; and I do hereby declarethat the following is a fun, clear, and exact description thereof.

I cut raw gntta percha'with a sufiicient quantity of h i-sulphuret of carbon or ben zine to reduce it to about theconsistency of cream. I then add about one part of sweet-oil to about thirty parts of the solution The oil is intended to render the cemented scam in the leather more elastic and pliable.

I also add a very small quantity of musk, or of the oil of rosemary about one part of musk to .one hundred of the compound. The musk or rosemary is used to counteract the disagreeable 'odorof the gutta percha.

It is applied by skiving thc'ends or edges of the leather to be cemented together, very thin, so as to present to each other as long a. lap as convenient. The cement is then applied, and the parts joined. The seam isthoroughly rubbed for a few minutes with a. smooth iron, or a rubber made of hard wood.

- v If a patch is to be applied to a boot or shoe, a last should be inserted, to keep the surface smooth while the seam isbeing rubbed.

The cement may be made applicable for cementing other articles, by adding one part of isinglass-glue to nine parts of the other ingredients.

What I claim as my invention, and desire to secure by Letters Patent, is The compound composed of the ingredients above set forth.
